IMPORTANT WARNING: Hydroxyurea can cause a severe decrease in the number of blood cells in your bone marrow. This may cause certain symptoms and may increase the risk that you will develop a serious infection or bleeding.
Stage IV colon cancer commonly spreads to the liver or the lungs. Some patients who have cancer that has spread to a single area are candidates for surgery to remove the metastases. Treatment of the liver: When itâs possible to completely surgically remove all liver metastases, surgery is the preferred treatment.
Treatment for colon cancer is based largely on the stage (extent) of the cancer, but other factors can also be important. People with colon cancers that have not spread to distant sites usually have surgery as the main or first treatment. Adjuvant (additional) chemotherapy may also be used.
